The Słupia, the Radunia, and the Wierzyca are rivers whose location and energy of water flow was taken advantage of to build hydroelectric power plants. Many of them are still operating and can be visited. The oldest such power plant in Europe, Struga, or the Radunia’s highest-situated plant in Bielkowo, are only a few of the facilities well worth seeing. The principles of physics, chemistry, and mathematics are contained in machines and post-industrial sites, and presented at thematic exhibitions, such as in the Hewelianum Centre.

The Skarszów Dolny hydroelectric power plant on the Skotawa

This power plant, dating back to the 1850's, is located in a scenic corner of the Skotawa.

For many years the facility was a hydro plant propelling the machines and appliances in the nearby ironware factory, and from 1872 in the paper mill. The factory was destroyed by a fire in 1984, and a hydroelectric plant was created on its foundations, with the current power of 160 KW. The facility went through modernisation during the war (1942-1943), and in 1955 a new concrete weir was added. The structure is composed of a three-span regulating weir which has a length of 6.30 m, a more than 1200 m-long approach flume, and a 40 m-long tressle for the power plant's two Francis turbines.
